Virginia Tech Researchers Develop Recyclable E-waste Solution
Updated June 03, 2025
The world’s growing mountain of electronic waste, or e-waste, poses a important environmental challenge. A united Nations report from 2024 revealed that global e-waste has surged from 34 billion to 62 billion kilograms in just 12 years. This amount, equivalent to 1.55 million shipping trucks, is projected to reach 82 billion kilograms by 2030. Alarmingly, only about 20% of this e-waste is currently recycled.
Now, researchers at Virginia Tech may have an answer to the e-waste problem. A new study published in Advanced Materials details a recyclable material that simplifies the breakdown and reuse of electronics, potentially boosting e-waste recycling efforts.
The team, led by Michael Bartlett, associate professor of mechanical engineering, and Josh Worch, assistant professor of chemistry, created a novel class of circuit materials. These circuits combine recyclability, electrical conductivity, reconfigurability, and self-healing properties wiht the strength of traditional circuit board plastics. This combination of features is rarely found in a single material.
The new material uses a vitrimer, a dynamic polymer that can be reshaped and recycled, combined with liquid metal droplets to conduct electricity. This approach differs substantially from conventional recyclable or flexible electronics.
“Our material is unlike conventional electronic composites,” Bartlett said. “The circuit boards are remarkably resilient and functional. Even under mechanical deformation or damage, they still work.”
Traditional circuit board recycling is energy-intensive and generates substantial waste, resulting in the loss of billions of dollars worth of valuable metal components. In contrast, the Virginia Tech team’s circuit board can be recycled easily.
“Traditional circuit boards are made from permanent thermosets that are incredibly tough to recycle,” Worch said. “Here, our dynamic composite material can be healed or reshaped if damaged by applying heat, and the electrical performance will not suffer.Modern circuit boards simply cannot do this.”
The vitrimer circuit boards can also be deconstructed using alkaline hydrolysis,allowing for the recovery of key components like liquid metal and LEDs. The team aims to fully reuse all components in a closed-loop process in future research.
What’s next
While curbing electronics consumption remains a challenge, this innovation marks a crucial step toward reducing e-waste in landfills and promoting sustainable e-waste management.
